To all whom it may concern;

Be it known that I, Donn AMERMAN,,-

a spring wheel comprising two or more spaced bands of resilient material which surround its felly, and spacing blocks beneath and over which the resilient bands bend when under load, the whole arrangewheel in a motor vehicle.

The invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claim.

In the drawings: Figure 1 is a side elevation of one-half of a wheel constructed in accordance with my invention, it being understood that the remaining half of the wheel is identical in construction with the portion shown. Fig. 2 is a fragmentary View, partly in side elevation and partly in vertical section, illustrating the manner 111-- which I prefer to connect the interposed spacing blocks. Fig. 3.is a transverse section takenin the plane indicated by the line 3-3 of 'Fig. 2.

' Similar letters, designate corresponding parts in all of the views of the drawings, referring to which:

be employed according to'ithe purposeto it will be called upon to bear.

At equidistant points around., tl1e felly 0' which the wheel is to be put and'the strains of the wheel and between the same andthe innermost band B, I arrange supporting blocks C for the band, and I fix the said blocks in position by radially disposed bolts 'D, which extend through the felly,;blocks andband. The said blocks C in common with the other blocks to be hereinafter described, may be formed of rubber'or other suitable resilient material, and are so formed when a highly resilient wheel is desired. I'- would have it understood, however, that I do not limit myself to the making of the said blocks of resilient material, inasmuch as they may be made of compressed aper, fiber, metal or other suitable matern and may be resilient or non-resilient in the discretion of the manufacturer of the wheel. If of metal, the blocks may also be and preferably-are welded to the band.

Intermediate the innermostband B and the next outer band B, I arrange supporting blocks C which are fixed to the two bands by radial bolts D, such as shown. If of metal the blocks may also be and preferably are welded to the bands.v This sec ond series of blocks 0' is arranged in such manner that each of the blocks comprised therein is arranged about midway between two of the blocks comprised in the inner series, this in order that the blocks of the inner series will not interfere with flattening or inward giving of the portions of the innermost band that occur between the said blocks, while the blocks of the second series will not interfere with inward giving or bending of the portions of the second hand.

that occur between the said blocks.

I Between the second band -and the outermost'band equidistant blocks G are placed and are secured by radial bolts D, as shown. If ofmetalithe blocks may also be and preferably. are welded to the bands. These latcular series are arranged about midway of that my novel wheel is simple and inexthe usage to which vehicle wheels are tic'ally noiseless or move'sidewise, and it will going that my improvement constitutes a eithera new wheel, or an old wheel of the resilient portions of the innermost and second bands, which obviously contributes tothe resiliency and at the same time increases the strength and durability of the wheel as a whole. I provide the outermost band with a tread E, of rubber or other suitable resilient material, and this tread may be secured on the band in the conventional or any other approved manner.

It will be gathered from the foregoing pensive, and is well adapted to withstand ordinarily subjected, since it does not embody any moving or sliding joints. It will also be gathered that the wheel is pracand is not liable: to creep further be appreciated that the flattening capacity of the band portionsthat occur between the supporting blocks enables the wheel to securely take hold of or grip the ground which is an important advantage. when the wheel is used as a traction wheel. will further be gathered from the forecushioning annulus which can be applied to ordinary construction in such manner as to surround the wheel with a view of preventing the transmission of shock and jar to the wheel and through the wheel to the vehicle of which the wheel forms apart.

While I have shown and described one form of my invention, it is to be understood that I am not limited to thedetails or the form or relative arrangement of parts disclosed, but that modifications may be made therein without departing from the spirit of the invention as claimed.

Having described -my invention, what I claim and desire to secure by Letters-Patent, is:

The herein described wheel, comprising a hub,'a felly, spokes interposed between the hub and the telly and connected therearranged opposite to, a resilient v Copies 01' this patent may be obtained for five cents each, by addressi metallic band, of larger diameter than the telly, surrounding and spaced from the fell supportin blocks arranged at intervals between the elly and the band; said blocks at their ends bearing directly against the felly and the band, radially disposed bolts one to each block, extending through the telly, the blocks and the band and having enlargements at their ehds; the enlargements in the band being flushwith the outer side thereof, a second resilient metal band, of larger diameter than the first-named 'band, surrounding and spaced from the latter, supporting blocks arranged at intervals between the bands and bearing directly at their ends against the bands, radially disposed bolts one to each block, extending through the bands and the blocks and having enlargements at their ends disposed in and arranged flush with the bands; the blocks of the set between the bands being arranged in radial aline'ment with the spokes, and the blocks of the set between the telly and the. inner band being the middles of the spaces between the blocks of the set between the bands, a channeled band resilient and of metal surrounding and spaced from the second-named band, supporting blocks arranged at intervals between the two outer bands and bearing directly at their ends against said bands, radially disposed bolts one to each block, outer bands and the blocks and having onlargements at their ends disposed in and arranged flush with said bands; the blocks of the set between the outer bands being disposed in radial alinement with the blocks between the telly and inner band, and a tread of resilient material carried in the channel of the outer band.

In testimony whereof I have hereunto set my hand in presence of two subscriblng witnesses. DORR AMERMAN. Witnesses:
